Subject: trace in kernel 4.1.5

Hi,

I didn't know where to leave this, so I e-mailed it to this e-mail address
as prescribed according to 
https://www.kernel.org/doc/Documentation/oops-tracing.txt

I did a iwconfig wlan0 txpower 0.
lspci gives me the following device for wlan0:
03:00.0 Network controller: Broadcom Corporation BCM43224 802.11a/b/g/n (rev
01)
I'm running this on a packard bell dot.nl/200 with most of the original
hardware.

I had a tail -f /var/log/syslog running.
root@...m:/var/log# iwconfig
wlan0     IEEE 802.11abgn  ESSID:off/any
